HUGH R. ROSS, OF BELFAST, IRELAND.

LOOM.

SPECIFICATION forming part of Letters Patent No. 679,429, dated. July 30, 1901. Application filed December 28, 1900. Serial No. 41,394. (No model.)

To (tZZ whom it may concern.-

Be it known that I, HUGH ROBERT Ross, 2. subject of the Queen of Great Britain, and a resident at Belfast, in the county of Antrim, Ireland, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates more particularly to looms in which the shuttle is removed or changed when the weft fails, such as described in the specification of my former patent, No. 631,407, of 1898. It may, however, be applied to any loom of this class or to other looms. It is designed to provide for the stopping of the loom when the shuttle has not reached or is absent from the shuttle-box 2 at the opposite end of the loom to the changebox. In a loom absence of shuttle means absence of weft, and in the ordinary loom the action of the weft-fork would without other stop-motion stop the loom. In this class of loom, however, in the absence of weft the action of the weft-fork brings another shuttle forward, so that the dying out of one shuttle might be immediately followed by another, and so on, until the stock was exhausted, leaving the loom working shuttleless.

The invention consists, essentially, in the application to or combination with the stopmotion attached to the shuttle-box of a reciprocating lever or its equivalent, which will throw the stop-motion out of action when the shuttle is in the change-box at the opposite end of the loom, or, in other words, will throw the stop-motion out of action at each alternative pick of the loom. It will be fully described with reference to the accompanying drawings, in which sufficient of the parts of a loom are shown to illustrate the invention.

Figure 1 is a side elevation of the stop-m0- tion from the end of the loom. Fig. 2 is a front elevation of same. Fig. 3 is a plan view; Fig. 4, a longitudinal sectional elevation of a shuttle-box placed at the other end of the loom; Fig. 5, a transverse sectional elevation of shuttle-box shown in Fig. at.

To the loom side or frame 1 (at the side opposite to the change-box) is fixed a frog a, (similar to that used in a fast-reed loom,) and to the shuttle-box 2, at the same side of the loom, is pivoted a finger b, which is lifted or operated by the swell c in the back of the shuttle-box 2. The swell o is pushed back by the shuttle as it enters the shuttle-box 2, and the finger Z) is lifted at the same time. When the finger b is raised by the swell c, it is lifted above and clear of the frog ct. The swell c engages against the upper part it of the pivoted finger or lever 19 to move it in one direction, and it and the swell are moved back again by the spring 6. The finger or lever 19 is pivoted upon the bar or rod 70 and is carried backward and forward with the reed 3.

The loom makes two picks and the reed 3 heats up twice for each entry of the shuttle into the shuttle-box 2. At one pick the shuttle enters the shuttle-box2 and the next pick the shuttle enters the change-box, leaving the shuttle-box 2 empty. To prevent the stopping of the loom when the shuttle-box 2 is empty and the shuttle is in the changebox, a reciprocating rod and lever d lifts the stop-lever b. The reciprocating lever d is operated from the bottom shaft 4 or other rotating part of the loom by a cam e and raises the finger I) clear of the frog (1 at each alternate pick or shot, and thus out of action, when the shuttle is in the change-box or shuttlebox 7, Figs. 4 and 5, at the opposite end of the loom.

The frog a slides to and fro on the frame 1, and it is moved in the direction to stop the loom by the lover I) and is pushed in the reverse direction backinto its normal position by the spring f. The frog a may come into direct contact with the setting-on lever 5 to stop the loom; but it is preferred to employ the second or intermediate lever g, pivoted to the frame side 1, with which the frog ct comes into contact, and which in turn acts.

upon the setting-on lever 5 to throw it off.

In a modification the pivoted finger or lever 12, attached to the shuttle-box, may come into direct contact with the setting-on lever 5, the frog a being dispensed with, the action of the shuttle in the shuttle-box and of the reciprocating lever at being to raise or move the pivoted finger b, so that it should not come into contact with the setting-on lever 5.

This stop-motion may also be applied to the plain boxes of ordinary change-box looms.

What I claim as my invention, anddesire to protect by Letters Patent, is-- 1. In a loom with a change-box at one end, the combination with the shuttle-box 2 and swell c therein at the other end and the pivoted finger or lever operated by the swell to operate the stop-motion when the shuttle is absent, of a reciprocating lever acting independently of the shuttle to lift the pivoted operating-lever out of action when the shuttle is in the opposite box substantially as described.

2. In a loom with change-box at one end, the stop-motion comprising a lever or finger pivoted to the shuttle-box at the other end operated by the swell, a frog sliding on the frame in contact with the setting-on lever 15 with which the finger engages, a reciprocating rod which lifts the finger out of operation when the shuttle is in the opposite box, and a cam by which the reciprocating rod is brought into action at each alternate pick substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
